用vue簡單的實現(xiàn)點擊按鈕切換背景顏色，具體代碼如下所示：

<div class='btnTitle'> <div : @click='changeBg(3)'>15天</div> <div : @click='changeBg(4)'>30天</div> </div> <div class='btnTitle'> <div : @click='changeBg(5)'>增量</div> <div : @click='changeBg(6)'>總量</div> </div> // 在methods方法里面 data () { time: 3, increase: 5, }, methods: { changeBg (index) { if (index === 3 || index === 4) { this.time = index } else if (index === 5 || index === 6) { this.increase = index } else { this.sort = index } } } // css樣式 <style lang='scss'>.bg { background-color: rgb(12, 197, 89); color: #fff; } .btnTitle { display: flex; width: 400px; border: 1px solid #ccc; background-color: #fff; margin-left: 10px; border-radius: 5px; .btn-bg { width: 50%; height: 40px; text-align: center; line-height: 40px; border-radius: 5px; } } </style>
